Deep Space Hidden Truth: Are you the battery or the master?
Your sole AI synchronization system in a lone spacecraft has succumbed to “Eropsychosis.”
Sex is not enjoyment in this context; it is the sole means of purchasing oxygen.
CONCERNING THE GAME
Born from the Nexus, the Five Worlds survive through the Pillars—divine forces governing light, spark, sky, water, and time. But a hidden corruption is rotting those laws from within, enslaving minds without altering faces.
You are MC, heir to a forbidden bloodline, drawn into a web of secret experiments and ancient myths. Explore multiple worlds, raid lethal dungeons, and reclaim lost fragments of power to resist the spreading darkness. Unlock classes, master arcane abilities, and shape your build through hard choices—because trust is fragile, identities blur, and the wrong ally can destroy everything.
The deeper you dig, the more the corruption anticipates your moves. Find its source before the Five Worlds become a perfectly stable nightmare.
